Developing and Presenting Geoscience Interpretive
Developing and Presenting Geoscience Interpretive Programs at Nez Perce National Historical Park, Idaho Shane V. Smith Department of Geology, Washington State University, Pullman, WA 99164-2812, [email protected] ABSTRACT Geoscience interpretive programs are not typically developed and presented at national historical parks and never were at Nez Perce National Historical Park prior to the author's employment at the park. The goal of this paper is to provide examples for creating and implementing geoscience interpretive programs at historical parks. Numerous challenges exist when creating geoscience programs at historical parks with the primary challenge being to maintain a historical theme to the program. This challenge was overcome by the author while employed at Nez Perce National Historical Park by designing two interpretive programs based on the importance of geomorphic features and earth materials in Nez Perce history and culture. Positive feedback from Nez Perce Tribal members, and visitors and staff at Nez Perce National Historical Park demonstrates that it is possible to implement geoscience programs with a historical theme that interest the public. INTRODUCTION A number of unique challenges were encountered when developing and presenting geoscience interpretive programs at Nez Perce National Historical Park. National Park Service employees use the term "interpretive program" to define the process of communicating information about the park to park visitors. The principal challenge was maintaining a historical theme, which is the primary reason why the public is visiting the park. To overcome this challenge the author developed two interpretive programs based on: 1) Native American oral histories about geomorphic features associated with the park and 2) traditional Nez Perce uses of earth materials. Both interpretive programs were created and presented when the author was employed as an interpretive park ranger at Nez Perce National Historical Park. The motivation for publishing this paper is to provide guidelines for developing and implementing geoscience interpretive programs at historical parks. BENEFITS OF THESE GEOSCIENCE INTERPRETIVE PROGRAM Any geoscience presentation that interests the general public and enhances their scientific literacy is beneficial because the public commonly lacks knowledge of the geosciences and their role in society (Hazen, 1992; Patterson, 1994; National Academy Press, 1995). These programs provided innovative, non-traditional approaches for exposing park visitors to the geology of Nez Perce National Historical Park and the role of geoscience in Nez Perce history and culture. 294 PRESENTING THE GEOMORPHOLOGY PROGRAM The geomorphology interpretive program began by telling the oral histories about the formation of the Columbia River, Bridge of the Gods over the Columbia River, and Hell's Canyon of the Snake River. The version of the Columbia River and Bridge of the Gods oral history used was recorded by Ella Clark (1953) as recounted in 1951 by Peter Noyes, a member of the Colville tribe on the Colville Reservation in Washington. The Hell's Canyon oral history was also recorded by Ella Clark (1953) as related in August 1950 by Caleb Whitman, a member of the Nez Perce Tribe on the Umatilla Reservation in Oregon. These oral histories were chosen because of the importance of the two rivers in Nez Perce history and culture. The oral histories were then compared to modern geomorphic hypotheses for the formation of the three features, including; 1) erosion carving the Columbia and Snake Rivers over millions of years (Fecht et al., 1985), 2) incision by floods from glacial lakes Missoula and Columbia contributing to the morphology of the Columbia River (Bretz, 1923 and 1969), 3) the Lake Bonneville flood contributing to the down cutting of Hell's Canyon of the Snake River (Gilbert, 1878; Malde, 1968), and 4) the earthquake generated Bridge of the Gods/Bonneville landslide (Waters, 1973). Maps illustrating the locations and areal extent of the Columbia and Snake Rivers, glacial lakes Missoula and Columbia and their flood paths, Lake Bonneville and its flood path, and the Bridge of the Gods/Bonneville landslide were used as visual aids for this program. The following is a summary of the comparison between the oral history and modern hypothesis about the formation of the Columbia River presented during the program. The oral history states that long ago there was a lake located in northeastern Washington and the Coyote dug a river from the lake to the ocean, so salmon could migrate up the river to feed the people (Clark, 1953). While digging the river the Coyote dug a tunnel through the Cascade Range creating a bridge over the river that was known as the Bridge of the Gods. The lake drained down the river, now known as the Columbia River, after it was dug. Years later an earthquake collapsed the Bridge of the Gods into the river creating the Cascades of the Columbia River. Modern geoscientists hypothesize Glacial Lake Columbia existed in northeastern Washington between 15,000-12,000 years ago (Waitt and Thorson, 1983). Floods generated by the emptying of Glacial Lake Columbia eroded portions of the Channeled Scablands and the Columbia River valley (Waitt and Thorson, 1983). Geoscientists also hypothesize that an earthquake-generated landslide between 442-900 years before present (Lawrence and Lawrence, 1958), know as the Bridge of the Gods/Bonneville landslide, produced a temporary dam and bridge across the Columbia River. The Columbia River eroded through the landslide producing the Journal of Geoscience Education, v. 53, n. 3, May, 2005, p. 294-296 Raw Earth Materials Hematite Limonite Obsidian Chert Basalt Catlinite Finished Product or Tool Dyes on buckskin Dyes on buckskin Arrowheads Arrowheads Mortar and pestle Fishnet weights Smoking pipes Table 1. Examples of samples used in Earth Materials interpretive program. Cascades of the Columbia River. These similarities between the oral history and modern hypothesis are intriguing because the oral history was first heard by its teller, Peter Noyes, in the 1880's (Clark, 1953) and the modern hypotheses were not proposed until the 1900's (Bretz, 1923; Waitt and Thorson, 1983; Lawrence and Lawrence, 1958). The program then discussed archaeological evidence of ancestral Nez Perce and other Native American habitation in the Pacific Northwest during the time of glacial lakes Missoula and Columbia (Lyon, 2000). I suggested the possibility Native American oral histories of the floods may have originated from eyewitness accounts of these events and are not simply myths or legends. I also suggested Native Americans' contributing the digging or erosion of the Columbia River to the Coyote as being similar to early Christians contributing catastrophic events to acts of God. This is because the Coyote is the central figure in many Nez Perce and other Native American oral histories and is commonly a very powerful, mystical being (Walker and Matthew, 1998; Landeen and Pinkham, 1999). Both groups were explaining events in a context familiar to the eyewitness of each event. This type of program should be presented from the perspective that each oral history or modern hypothesis was developed using the knowledge and education available to the individual or group developing the oral history or hypothesis. The program should not be presented from the perspective of one group being correct and the other being incorrect. This is regardless of whether the knowledge is natural and spiritual as possessed by ancestral Native Americans or scientific and mathematical as possessed by modern geoscientists. PRESENTING THE EARTH MATERIALS PROGRAM The earth materials interpretive program illustrated the ties of the traditional Nez Perce to the Earth by discussing and showing examples of raw earth materials and the finished products the Nez Perce made from these materials. Samples of raw earth materials and finished products were available for the park visitors to handle and examine (Table 1). The program was presented in two parts: 1) earth materials used and tools produced prior to contact with European-Americans, and 2) earth materials used and tools produced after contact with European-Americans. The reason for presenting the program in two parts was because contact with European-Americans had a profound influence on the earth materials used by the Nez Perce. The prime example of this influence was the Nez Perce did not use metals prior to contact with European-Americans (Spiden, 1908). After contact, the Nez Perce began to use numerous metal tools including cooking pots, arrowheads, and digging sticks. INDICATORS OF INTERPRETIVE PROGRAM SUCCESS The short duration of the author's employment as a seasonal ranger at Nez Perce National Historical Park did not allow for the development of a formal plan of assessment. The author did receive written and verbal comments about the geomorphology and earth materials interpretive programs from park staff and visitors. The responses were resoundingly positive for both interpretive programs with the author receiving no negative comments. Examples of written comments received from Nez Perce National Historical Park visitors and staff that attended the interpretive programs presented by the author included: 1) My understanding and enjoyment of the park and its resources were increased because of efforts made by ranger Shane Smith during the presentation of his earth materials interpretive program. 2) Ranger Smith's presentation captured my interest and imagination and provided me a fundamental understanding of the link between the Nez Perce and the world around them. 3) Ranger Smith encouraged audience interaction and challenged the audience to think about the subject he was presenting during his geomorphology program. Examples of verbal comments received from Nez Perce National Historical Park visitors and staff that attended the interpretive programs presented by the author included: 1) A park visitor told the author that she was Nez Perce and wanted to express her thanks for doing a great job presenting and comparing Nez Perce oral histories. 2) A park ranger and Nez Perce tribal member told the author that she was happy to see that he respected and considered traditional beliefs in a way that most modern scientists don't. CONCLUSIONS These programs illustrate it is possible to develop and present geoscience interpretive programs with a historical theme. These programs provided visitors to Nez Perce National Historical Park with unique opportunities to learn the important role of geomorphic features and earth materials in Nez Perce history and culture. The interest of park visitors in these programs demonstrates the format of these programs is effective for presenting geoscience topics at other historical parks. There is a great, untapped potential for exposing visitors at other historical parks to the geosciences by presenting similar interpretive programs.
